Adjusting Sensor Output After Sensor Replacement

Perform the following steps whenever you replace the Punch Controller Board,
horizontal registration sensor (photosensor board/LED board), or waste full sensor
(waste full photosensor board/waste full LED board):
1. Locate DIP switches SW1001, SW1002, and SW1003 and LEDs LED1001,
LED1002, and LED1003 on the Punch Controller Board.
2. For DIP switch SW1001 on the Punch Controller Board, press shift bits 1
through 4 as follows:
3. Press switches SW1002 or SW1003 on the Punch Controller Board:
Pressing either switch will adjust the sensor output.
The adjustment is complete when all LEDs on the Punch Controller Board
are ON for LEDS LED1001, LED1002, LED1003.
4.
Shift all bits of DIPSW1001 to OFF (this action ensures that the LEDs will
remain unaffected and the switch setting will have no further effect).
